SOmeone apparently has to point out the obvious to the people entrusted with doing something to address those flaws, or it is guaranteed that they will be exploited by an astute enemy. If working within the system will not get those flaws addressed, then ripping the lid off can. Otherwise, the flaws will continue to exist, and as I pointed out, will be obvious to any enemy professional, whether the amatuers at TSA are willing to admit they exist or not.
The current circus theater being called "security", could be a lot less invasive and more effective if it were oriented toward security and not politicized to the point of ineffectiveness. At best, every security measure has been a reactive one, closing the barn door behind the vanishing horses.
If you aren't thinking ahead of your enemy, he is thinking ahead of you. At least someone had the stones to point that out in a way which might have embarassed some people, but might close some windows of opportunity before they are used against the public. YMMV, but as I mentioned, the planners, the professionals on the other side would be able to spot the flaws without any help.
None of what you say addresses the main point - one should NEVER willingly provide an enemy with security information - EVER. So your attempted points make no sense unless you hate the TSA worse than Al Qaeda.
